Abstract:
The effect of spraying 50% difenoconazole-sulfur water dispersible granule against watermelon powdery mildew was studied by spraying method.The results showed the best amount of 50% difenoconazole-sulfur water dispersible granule was 80 g per 667 m2.Seven days after the second spraying，the control effect reached 70.81%，and it reached 83.28% seven days after the fourth spraying.The control effect were more significant than that of 250 g?L-1 of difenoconazole EC and 80% sulfur WG.Therefore, it was suggested to dilute 50% difenoconazole-sulfur water dispersible granule to 900-1 200 times before use.
